The original page can still be visited. That the birthplace of Japan's internet presence was a high-energy physics lab rather than a tech company is no accident -- KEK, the High Energy Accelerator Research Organization, has been at the frontier of Japanese science for decades, operating particle accelerators that smash electrons and positrons together at nearly the speed of light beneath the Ibaraki countryside. With approximately 695 employees and collaborators from hundreds of institutions worldwide, KEK's campus is one of those places where the questions being asked are so fundamental -- why does matter exist at all? -- that the machines built to answer them stretch for kilometers underground.

It emerged from the merger of three institutions: the Institute of Nuclear Study at the University of Tokyo, founded in 1955; the National Laboratory for High Energy Physics, established in 1971; and ...

Two storage rings -- one pushing electrons to 7 GeV, the other accelerating positrons to 4 GeV -- send particles hurtling in opposite directions before smashing them toge...

Makoto Kobayashi, emeritus professor at KEK, shared the 2008 Nobel Prize in Physics for his theoretical work on CP-violation -- the subtle asymmetry between matter and antimatter that helps explain why the universe contains matter at all rather than having annihilated itself in t...

Before SuperKEKB, the same tunnel housed TRISTAN -- the Transposable Ring Intersecting Storage Accelerator in Nippon -- an electron-positron collider that operated from 1987 to 1995 hunting for the top quark at energies up to 30 GeV. TRISTAN never found the top quark (Fermilab cl...
